Thank You All for Your Info & Help. The present wiper system works fine & I acquired a complete 2 bladed system for backup/parts/etc; just in case. One last question on wipers:
Is the wiper linkage adjustable, ie. shorten or lengthen the arc? You'll all be happy to know that a service manual will show up shortly & I will be able to leave you alone. I enjoy the 190e i purchased. I just finished a 1986 Saab Turbo that is now all SPG spec, except for aero panels. Not needed IMHO. For the 190e, I will just refurbish & enjoy. Next project on it is to R/R Sunroof for guide & tube cleaning/lube. It is DIRTY in there :-(
Thanks Again;
Richard
